Available in PDF, EPUB and Kindle. Book excerpt: The Sixth Refinement Workshop took place at City University in London from 5th to 7th January 1994. The present volume includes all of the papers which were submitted and accepted for presentation, together with two papers by invited speakers. The workshops in the series have generally occurred at one year intervals but in this last case a two year period had elapsed. These workshops have established themselves as an important event in the calendar for all those who are interested in progress in the underlying theory of refinement and in the take-up by industry of the methods supported by that theory. One of the proposed themes of the sixth workshop was the reporting of successful adoption in industry of rigorous software development methods. The programme committee was perhaps slightly disappointed by the response from industry to the call in this respect. However, the recent period could be characterised as one of consolidation, when those companies which have made the decision that formal development methods are important to their business have been adopting them where appropriate and finding them to be worthwhile. On the other hand,. the difficult economic climate which exists in most parts of the developed world is perhaps not the context within which companies still dubious about the benefits are goil'\g to opt for making major changes in their working practices.

Download or read book 5th Refinement Workshop written by Cliff B. Jones and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: Refinement is the term used to describe systematic and formal methods of specifying hard- and software and transforming the specifications into designs and implementations. The value of formal methods in producing reliable hard- and software is widely appreciated by academics and workers in industry, despite the fact that certain research areas, such as the application to industrial-scale problems, are still in their infancy. This volume contains the papers presented at the 5th Refinement Workshop held in London, 8-10 January 1992. Its theme was the theory and practice of software specifications, which is the transformation of formal software specifications into more correct specifications, designs and codes. This has been an important area of research for the last 5 years and the workshop addressed specific issues and problems related to it. Among the topics discussed in this volume are: the role of refinement in software development, parallel designs and implementations, methods and tools for verification of critical properties, refinement and confidentiality, concurrent processes as objects, the compliance of Ada programs with Z specifications and a tactic driven refinement tool. This is the latest refinement workshop proceedings to be published in the Workshops in Computing series (the 3rd and 4th workshops having appeared in 1990 and 1991 respectively). It will be of interest to academic and industrial researchers, postgraduate students and research-oriented developers in the computer industry.

Available in PDF, EPUB and Kindle. Book excerpt: Since its conception nearly 20 years ago, Logic Programming - the idea of using logic as a programming language - has been developed to the point where it now plays an important role in areas such as database theory, artificial intelligence and software engineering. However, there are still many challenging research issues to be addressed and the UK branch of the Association for Logic Programming was set up to provide a forum where the flourishing research community could discuss important issues of Logic Programming which were often by-passed at the large international conferences. This volume contains the twelve papers which were presented at the ALPUK's 3rd conference which was held in Edinburgh, 10-12 April 1991. The aim of the conference was to give a broad but detailed technical insight into the work currently being done in this field, both in the UK and by researchers as far afield as Canada and Bulgaria. The breadth of interest in this area of Computer Science is reflected in the range of the papers which cover - amongst other areas - massively parallel implementation, constraint logic programming, circuit modelling, algebraic proof of program properties, deductive databases, specialised editors and standardisation. The resulting volume gives a good overview of the current progress being made in the field and will be of interest to researchers and students of any aspects of logic programming, parallel computing or database techniques and management.

Available in PDF, EPUB and Kindle. Book excerpt: Architectures and tools are two important considerations in the construction of interactive computer systems. The former is concerned with the optimal structural organisation of systems and the latter with the effective support of the design and management of user interfaces. They are regarded as the areas of research most likely to contribute to the development of existing interactive systems, in particular by providing improved architectures capable of supporting new styles of interaction and more sophisticated software tools to improve productivity. This volume combines the proceedings of two workshops held in York and Glasgow which concentrated on architectures and tools respectively. In doing so it addresses the problems of user interface construction from two complementary viewpoints and provides alternative perspectives on many of the central issues. Some of the papers are published in expanded form to provide a more comprehensive coverage of the topics and two additional papers have been included which offer a useful insight into issues raised by the workshops. The papers address formal and theoretical concerns as well as academic and commercial ones. Specific topics covered include novel-input models, architectures for real-time systems and object-oriented user interface tools for X-widgets, NeWS- and Smalltalk-based applications. The papers also include presentations of new tools and architectural designs. Building Interactive Systems: Architectures and Tools provides the most extensive recent account of research into the relationship between architectures and tools in the construction of interactive computer systems and will be of interest to researchers, postgraduate students and software developers.

Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the proceedings ofthe 4th Refinement Workshop which was organised by the British Computer Society specialist group in Formal Aspects of Computing Science and held in Wolfson College, Cambridge, on 9-11 January, 1991. The term refinement embraces the theory and practice of using formal methods for specifying and implementing hardware and software. Most of the achievements to date in the field have been in developing the theoretical framework for mathematical approaches to programming, and on the practical side in formally specifying software, while more recently we have seen the development of practical approaches to deriving programs from their speCifications. The workshop gives a fair picture of the state of the art: it presents new theories for reasoning about software and hardware and case studies in applying known theory to interesting small-and medium-scale problems. We hope the book will be Of interest both to researchers in formal methods, and to software engineers in industry who want to keep abreast of possible applications of formal methods in industry. The programme consisted both of invited talks and refereed papers. The invited speakers were Ib S0rensen, Jean-Raymond Abrial, Donald MacKenzie, Ralph Back, Robert Milne, Mike Read, Mike Gordon, and Robert Worden who gave the introductory talk. This is the first refinement workshop that solicited papers for refereeing, and despite a rather late call for papers the response was excellent.

Download or read book Rules in Database Systems written by Norman W. Paton and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 419 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the proceedings of a workshop held at Heriot-Watt University in Edinburgh in August 1993. The central theme of the workshop was rules in database systems, and the papers presented covered a range of different aspects of database rule systems. These aspects are reflected in the sessions of the workshop, which are the same as the sections in this proceedings: Active Databases Architectures Incorporating Temporal Rules Rules and Transactions Analysis and Debugging of Active Rules Integrating Graphs/Objects with Deduction Integrating Deductive and Active Rules Integrity Constraints Deductive Databases The incorporation of rules into database systems is an important area of research, as it is a major component in the integration of behavioural information with the structural data with which commercial databases have traditionally been associated. This integration of the behavioural aspects of an application with the data to which it applies in database systems leads to more straightforward application development and more efficient processing of data. Many novel applications seem to need database systems in which structural and behavioural information are fully integrated. Rules are only one means of expressing behavioural information, but it is clear that different types of rule can be used to capture directly different properties of an application which are cumbersome to support using conventional database architectures. In recent years there has been a surge of research activity focusing upon active database systems, and this volume opens with a collection of papers devoted specifically to this topic.

Download or read book Specifications of Database Systems written by David J. Harper and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: Increasingly, formal specification is being used by database researchers to describe and understand the systems they are designing and implementing. Similarly, those working on formal specification techniques have recognised that the database field provides a rich context for developing their ideas. However, as experts in one field often have a relatively limited knowledge of the other, there is a growing need for discussion about the relationship between these two fields and how they can be usefully combined. This volume contains the 16 papers which were presented at the International Workshop on Specification on Database Systems, held in Glasgow, 3-5 July 1991. The purpose of the workshop was to bring together these fields and to examine, through a series of invited talks, presentations and working groups, the role that formal specification can play in developing database systems. The papers describe current research into topics such as the formal specification of data models, query languages and transaction handling and the use of formal specification techniques to understand problems which arise in database systems. The working groups, which are summarised at the end of the volume, covered a variety of issues including the role of graphical notations in database specification, the use of specification techniques in enabling "open" or extensible database systems and the education of the database community in specification techniques. This volume will be invaluable to the increasing number of researchers who are using both database systems and formal specification techniques in their work, and who wish to gain a more detailed knowledge of these two fields and the issues which affect them.

Download or read book Code Generation — Concepts, Tools, Techniques written by Robert Giegerich and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 323 pages. Available in PDF, EPUB and Kindle. Book excerpt: Code Generation - Concepts, Tools, Techniques is based upon the proceedings of the Dagstuhl workshop on code generation which took place from 20-24 May 1991. The aim of the workshop was to evaluate current methods of code generation and to indicate the main directions which future research is likely to take. It provided an excellent forum for the exchange of ideas and had the added advantage of bringing together European and American experts who were unlikely to meet at less specialised gatherings. This volume contains 14 of the 30 papers presented at the Dagstuhl workshop. The papers deal mainly with the following four topics: tools and techniques for code generation, code generation for parallel architectures, register allocation and phase ordering problems, and formal methods and validations. Most of the papers assess the progress of on-going research work, much of which is published here for the first time, while others provide a review of recently completed projects. The volume also contains summaries of two discussion groups which looked at code generation tools and parallel architectures. As a direct result of one of these discussions, a group of the participants have collaborated to make a pure BURS system available for public distribution. This system, named BURG, is currently being beta-tested. Code Generation - Concepts, Tools, Techniques provides a representative summary of state-of-the-art code generation techniques and an important assessment of possible future innovations. It will be an invaluable reference work for researchers and practitioners in this important area.

Download or read book Designing Correct Circuits written by Geraint Jones and published by Springer Science & Business Media. This book was released on 2013-12-14 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: These proceedings contain the papers presented at a workshop on Designing Correct Circuits, jointly organised by the Universities of Oxford and Glasgow, and held in Oxford on 26-28 September 1990. There is a growing interest in the application to hardware design of the techniques of software engineering. As the complexity of hardware systems grows, and as the cost both in money and time of making design errors becomes more apparent, so there is an eagerness to build on the success of mathematical techniques in program develop ment. The harsher constraints on hardware designers mean both that there is a greater need for good abstractions and rigorous assurances of the trustworthyness of designs, and also that there is greater reason to expect that these benefits can be realised. The papers presented at this workshop consider the application of mathematics to hardware design at several different levels of abstraction. At the lowest level of this spectrum, Zhou and Hoare show how to describe and reason about synchronous switching circuits using UNilY, a formalism that was developed for reasoning about parallel programs. Aagaard and Leeser use standard mathematical tech niques to prove correct their implementation of an algorithm for Boolean simplification. The circuits generated by their formal synthesis system are thus correct by construction. Thuau and Pilaud show how the declarative language LUSTRE, which was designed for program ming real-time systems, can be used to specify synchronous circuits.

This book was released on 2012-12-06 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is many years since Landin, Burge and others showed us how to apply higher order techniques and thus laid some foundations for modern functional programming. The advantage of higher order descriptions - that they can be very succinct and clear - has been percolating through ever since. Current research topics range from the design, implementation and use of higher order proof assistants and theorem provers, through program specification and verification, and programming language design, to its applications in hardware description and verification. The papers in this book represent the presentations made at a workshop held at Banff, Canada, September 10-14 1990 and organised by the Computer Science Department of the University of Calgary. The workshop gathered together researchers interested in applying higher order techniques to a range of problems. The workshop format had a few (but fairly long) presentations per day. This left ample time for healthy discussion and argument, many of which continued on into the small hours. With so much to choose from, the program had to be selective. This year's workshop was divided into five parts: 1. Expressing and reasoning about concurrency: Warren Burton and Ken Jackson, John Hughes, and Faron Moller. 2. Reasoning about synchronous circuits: Geraint Jones and Mary Sheeran (with a bonus on the fast Fourier transform from Geraint). 3. Reasoning about asynchronous circuits: Albert Camilleri, Jo Ebergen, and Martin Rem. 4. Categorical concepts for programming languages: Robin Cockett, Barry Jay, and Andy Pitts.

This book was released on 2013-06-29 with total page 203 pages. Available in PDF, EPUB and Kindle. Book excerpt: Performance engineering is a fast-moving field where advances in technology mean that new issues constantly need to be addressed. In response to this, the UK Computer and Telecommunications Performance Engineering workshops were set up in 1985 to provide a valuable opportunity for the discussion and exchange of ideas. They have subsequently become well established as the focus for academic and industrial practitioners from the UK and Europe with an interest in performance and modelling and analysis. This volume contains the 16 papers which were presented at the 7th annual workshop, held in Edinburgh in July 1991. The workshop highlighted various aspects of parallel computing - an area which is attracting an increasing amount of interest - and the work presented in these papers is of particular interest as the contributors used real analysis to evaluate their models. The papers cover an unusually wide range of topics, both practical and theoretical, including advances in queueing theory, common performance problems and their solutions, assessments of available tools and presentations of new theoretical results. The result is an extremely comprehensive coverage of this important and challenging field. This volume provides an up-to-date assessment of work being carried out by performance engineers in the UK and Europe and will be an invaluable reference book for researchers and practitioners wishing to familiarise themselves with the benefits of performance and analysis.

Available in PDF, EPUB and Kindle. Book excerpt: In ordinary mathematics, an equation can be written down which is syntactically correct, but for which no solution exists. For example, consider the equation x = x + 1 defined over the real numbers; there is no value of x which satisfies it. Similarly it is possible to specify objects using the formal specification language Z [3,4], which can not possibly exist. Such specifications are called inconsistent and can arise in a number of ways. Example 1 The following Z specification of a functionf, from integers to integers "f x : ~ 1 x ~ O· fx = x + 1 (i) "f x : ~ 1 x ~ O· fx = x + 2 (ii) is inconsistent, because axiom (i) gives f 0 = 1, while axiom (ii) gives f 0 = 2. This contradicts the fact that f was declared as a function, that is, f must have a unique result when applied to an argument. Hence no suchfexists. Furthermore, iff 0 = 1 andfO = 2 then 1 = 2 can be deduced! From 1 = 2 anything can be deduced, thus showing the danger of an inconsistent specification. Note that all examples and proofs start with the word Example or Proof and end with the symbol.1.

This book was released on 2012-12-06 with total page 492 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume results from the regular sessions of the Second International Workshop of the Moscow ACM SIGMOD Chapter "Advances in Databases and Information Systems" (ADBIS'95) that took place 27th-30th June 1995, in Moscow, Russia. ADBIS'95 continues a series of annual Workshops on Advances in Databases and Information Systems organized by the Moscow ACM SIGMOD Chapter in cooperation with the Russian Founda tion for Basic Research. Past successful ADBIS conferences include the ADBIS'93 and ADBIS'94 Workshops that took place in Moscow. The aims of these workshops are to provide a forum for the presentation and in-depth discussion of advanced research directions that will effectively improve the building and use of future information systems and to increase communication between the Eastern and Western research communities which were formerly separated and still have only rare possibilities to interact. Improving of the contacts and exchange of ideas between researchers from the East and from the West will eventually lead to better collaboration between them. The ADBIS'95 Call for Submissions attracted 60 submissions from 15 countries of which 35 submissions were accepted for presentation at the regular sessions, 9 as posters, and 7 as presentations for a special session for the Information Systems for Science. This volume contains the papers presented in the regular sessions.

Download or read book Software Re-use, Utrecht 1989 written by Liesbeth M. Dusink and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: In November 1989 we organised a workshop on software re-use, inviting members of the leading research teams across Europe. In retrospect, we realise that we missed a few research teams out, but nevertheless we did have a very fruitful workshop. This book is the outcome of that meeting. Prior to the workshop, teams submitted short position papers, and at the workshop made very short presentations of these. Most of the time was spent in four parallel sessions, and the reports of these sessions are given in Chapter 2. After the workshop we invited the attendees to revise and resubmit their papers in the light of the workshop, and it is these updated papers that appear in Chapter 4 onwards. The papers are in alphabetical order of first author. To complete this text we have added an introduction to software re-use as a first chapter-this was prepared by Liesbeth Dusink. We have added a comprehensive bibliography as Chapter 3, merging the bibliographies accumulated at Delft and at Brunei. To be able to organise the workshop we were sponsored by SERC, the Software Engineering Research Centre in Utrecht, Netherlands.
